You mean the output is happening through GDB. The point is that this output
is encoded in a GDB packet, received by GDB and displayed by GDB.

GDB doesn't support getting characters from the keyboard and sending them
over serial to the target.

If you require serial input, you will have to disconnect from GDB and use
the serial port directly. You will also need to enable the eCos serial
device driver on the AEB.
